if that was me, with your use of smoke, and your light and your smoking body, I would just grow less plants at the time, maybe just two, give em more attention/love and space and I bet, yield almost the same, less work, less risk, less money spend, and still enough smoke for yourself and some
and maybe use the "some" to "give" away for favors... and no not them you think of... a bottle of nutrients or some new seed`s etc. so your grow cost is minimum
my goal would be to grow almost for free and have beautiful plants that had plenty of space/light and enjoy it, wile I made sure me smoking body and I had plenty, much more fun to have two plant`s going all the time then 4 every half year, give the two, more room time and space and Im sure they will reward you both in the fun and yield department
